Babies in popular low-riding pushchairs are exposed to alarming levels of toxic air pollutants Posted: 08 Apr 2020 11:58 AM PDT Parents who are using popular low-riding pushchairs could be exposing their babies to alarming levels of air pollution, finds a new study. |
Origins of Earth's magnetic field remain a mystery Posted: 08 Apr 2020 11:27 AM PDT The existence of a magnetic field beyond 3.5 billion years ago is still up for debate. |
Don't look to mature forests to soak up carbon dioxide emissions Posted: 08 Apr 2020 08:33 AM PDT Research suggests mature forests are limited in their ability to absorb 'extra' carbon as atmospheric carbon dioxide concentrations increase. |
Earliest humans in the Amazon created thousands of 'forest islands' as they tamed wild plants Posted: 08 Apr 2020 08:03 AM PDT The earliest human inhabitants of the Amazon created thousands of artificial forest islands as they tamed wild plants to grow food, a new study shows. |
Climate change could cause sudden biodiversity losses worldwide Posted: 08 Apr 2020 08:03 AM PDT A warming global climate could cause sudden, potentially catastrophic losses of biodiversity in regions across the globe throughout the 21st century, finds a new study. |
New study helps improve accuracy of future climate change predictions Posted: 08 Apr 2020 07:49 AM PDT New research has shone light on the impact of clouds on climate change. The study has raised serious doubts of the likely impact of human-led interventions involving methods of cloud 'brightening' to counteract climate change. |
Lobster digestion of microplastics could further foul the food chain Posted: 08 Apr 2020 07:49 AM PDT Tiny fragments of plastic waste are dispersed throughout the environment, including the oceans, where marine organisms can ingest them. However, the subsequent fate of these microplastics in animals that live near the bottom of the ocean isn't clear. Now, researchers report that lobsters can eat and break down some of this microplastic material, releasing even smaller fragments into the water that other deep-sea organisms could ingest. |
Posted: 08 Apr 2020 07:21 AM PDT A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift -- a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean. |
How does habitat fragmentation affect Amazonian birds? Posted: 08 Apr 2020 05:55 AM PDT The Biological Dynamics of Forest Fragments Project (BDFFP), located near Manaus, Brazil, began in 1979 and is the world's longest-running experimental study of tropical forest fragments. A new article summarizes four decades of data from the project about how Amazonian bird communities respond to habitat fragmentation, a question as relevant today as ever in light of the recent increase in deforestation in the Amazon. |
What are the environmental impacts of cancer drugs? Posted: 08 Apr 2020 05:55 AM PDT Chemotherapeutic drugs, also known as antineoplastic agents, that are prescribed to treat a range of cancer types, enter the aquatic environment via human excretion and wastewater treatment facilities. A review indicates that very few studies have characterized the effects of antineoplastic agents that are released into aquatic environments. |
The link between virus spillover, wildlife extinction and the environment Posted: 07 Apr 2020 06:56 PM PDT As COVID-19 spreads across the globe, a common question is, can infectious diseases be connected to environmental change? Yes, indicates a new study. Exploitation of wildlife by humans through hunting, trade, habitat degradation and urbanization facilitates close contact between wildlife and humans, which increases the risk of virus spillover, the study found. Many of these same activities also drive wildlife population declines and the risk of extinction. |
